After Stage 1 installation, it was 5.452sec!!
(I tried several times. As average, it was around 5.5sec.)

Again, I didn't do any tuning without BMS JB Stage 1.
Default boost is still +3psi. (Not changed.)
I didn't use a launch control.

I got 0-60 time with Torque Pro app / OBD2 adapter.

Here is an evidence.

I wanna try with +4psi at some future date ;-)

If you measured 0-100 time, note that 100 km/h is about 62.1mph.
Also BMS test car has a pneumatic wastegate and a sport auto tranny.

No, I got it as 0-60mph. 0-100km/h was 5.629sec with stage 1.
Again, my car was stock without stage 1 !

I have the same setup (stock + auto + use torque pro) and getting similar number, but I think it was 5.8~5.9 stock and 5.5~5.6 with stage 1. I am still curious how much better is stage 2, I mean, for $175, it is not bad to give it a try but I am still thinking cause it is still in beta and with the N26 electronic solenoid, I am afraid the gain is minimal. Anyone else try?

Same car here (no 4x4 though). I'm trying to find the same answer but haven't had much luck.

So I have a question. I went from a Cobb tuned E90 to a untuned F30 N20. It's got a lot of spunk for sure, but I've been reading about the JB. My question is does this work like the ones for the E90 where you change maps and enable by the steering wheel, or is this always on and no way to disable? Lastly how easy is it to install and take off and does doing so cause any codes? Thanks
